This page lists everything OwnerSpec stores on your device. It is the detail behind the
banner; the wider picture is in our [privacy policy](/legal/privacy/).

## How consent works here

- **In the EEA, the UK and Switzerland, nothing optional loads before you decide.** Analytics
  scripts are injected only after a yes. Before that, no Google or Microsoft cookie exists on
  your device.
- **Reject is one click, in the same place as Accept.** Refusing costs you nothing and the
  site is fully usable.
- **You can change your mind at any time** with the "Cookie settings" link in the footer of
  every page. Choosing "Reject" there also deletes the analytics cookies already set.
- **If you are in the EEA, the UK or Switzerland,** we ask before anything loads. Elsewhere,
  analytics start without a banner: this policy is the notice, and the "Cookie settings" link
  in the footer is a standing opt-out.
- If we cannot tell where you are, we ask. Failure always defaults to the stricter option.

## Strictly necessary

These are required for the site to function and to record your own choice. They are not
optional and cannot be switched off.

| Name | Type | Purpose | Duration |
|---|---|---|---|
| `os_consent` | Local storage | Records your consent choice, the date and the policy version. This is what stops us asking on every page. | Until cleared or the policy version changes |
| `os-loc` | Session storage | Your country as reported by the Cloudflare edge, so the correct consent interface is shown. | Until the tab is closed |
| `__cf_bm`, `cf_clearance` | Cookie (Cloudflare) | Bot management and security. Set by our host. | 30 minutes to 1 year |

## Analytics, only after consent

| Name | Set by | Purpose | Duration |
|---|---|---|---|
| `os_uid` | OwnerSpec | A random visitor id, shared with Google Analytics and Microsoft Clarity so a returning visit is counted as returning. Not derived from you and never linked to a name or email. | 1 year |
| `_ga` | Google Analytics | Distinguishes visitors | 2 years |
| `_ga_<id>` | Google Analytics | Maintains session state | 2 years |
| `_clck` | Microsoft Clarity | Persists a Clarity user id | 1 year |
| `_clsk` | Microsoft Clarity | Links page views into one session | 1 day |
| `CLID`, `ANONCHK`, `MR`, `MUID`, `SM` | Microsoft | Clarity session and measurement | Session to 1 year |

These transfer data to the United States. See section 4 of the
[privacy policy](/legal/privacy/#4-transfers-outside-the-eea).

## Advertising

None. OwnerSpec runs no ad network and no remarketing. Google's advertising consent signals
(`ad_storage`, `ad_user_data`, `ad_personalization`) are held at *denied* permanently, even
when you accept analytics.

## Merchant cookies on outbound links

If you click an affiliate link, the merchant sets its own cookies on its own domain under its
own policy. Amazon's association cookie, for example, lasts 24 hours. We cannot set, read or
delete those, and refusing analytics here has no effect on them. Your browser's own cookie
controls do.

## Controlling cookies in your browser

Every major browser lets you block or delete cookies and clear local storage for a single
site. Blocking strictly necessary items may mean we ask for consent again on each visit.
